All,
I found this problem with IE9 while trying to create a new replication job after our IT group installed the KB2846071 patch on our Windchill servers and clients.
The selection of the replication vault step in the wizard failed to display, or gave me a PickerInputComponentCallback exception when I selected a replication vault and proceeded to the next step, it then closed the wizard completely.
I remembered seeing something about this patch mentioned on one of the solutions threads, so I looked it up.
After installing the workaround mentioned in CS134791, and clearing the IE client cache files, it fixed the problem.
Thank you Brian, for bringing up this problem to the solutions group, and supplying the reference to fix it.
